The term is also commonly used when discussing digital
sampling and sample rates. For example, the MP3 audio
compaction algorithm is often set to ouput files with a
bitrate of 120 kbps. This means that the file contains an
average of 120 kilobits for each second of audio (900 KB per
minute). This compares with CD audio which is encoded at
44100 16-bit stereo samples per second or 1408 kbps.
